Skin fold in the transient electric field
QuickField simulation example
Skin fold is placed between two flat electrodes with the voltage pulses applied.
Problem Type
Plane-parallel problem of Transient electric.
Geometry
Given
Voltage V~ = 500 V, pulse duration 70μs.
| Tissue name | Thickness, μm | Relative dielectric permittivity | Conductivity, mS/m |
|---|---|---|---|
| Stratum corneum | 5 | 10k | 0.0125 |
| Epidermis | 10 | 1.2M | 227 |
| Dermis | 700 | 1.2M | 227 |
| Muscle | 550 | 25M | 400 |
| Sub tissue | 495 | 10M | 20 |
Task
Simulate the transient electric field stress and current distribution in the fold of the skin.
Solution
The voltage pulse is defined by the formula 500*impulse(t,0,70e-6)
